6.1.2 Alarm Maintenance

Maintenance Link Failure
Context
If ALD Maintenance Link Failure is reported during AISU operation and maintenance, the
eNodeB determines whether to clear the alarm or not based on the actual link conditions.
Table 6-3 describes the maintenance link failure symptom.
Table 6-3 Symptom
Symptom
The eNodeB
periodically checks
the AISG link status
of the AISU. When
the AISG link is
abnormal, the
eNodeB reports
ALD Maintenance
Link Failure.
Figure 6-1 shows the detailed information about ALM-26541 ALD Maintenance Link Failure.
Issue 02 (2017-06-12)
If the alarm is cleared, no further action is required.
If the alarm persists, go to section "Maintenance Link Failure."
Impact on the
System
The AISU
maintenance link is
disconnected. As a
result, the AISU
cannot be
configured, and
antenna engineering
parameters cannot
be obtained.
